The "down-to-earth" divorcee lists overseas travel, music, sports, cooking and reading as his main interests.

He credits a good sense of humour, work/life balance and the ability to laugh at yourself as desirable qualities in a potential wife and travel partner.

"If you think Paris is the most beautiful city in the world, tell your parents to get ready for the wedding," he writes.

However, those hoping to secure a date with Mr Engle must first provide a photo and answer no less than 21 questions about themselves, including "On a scale of 1-5 how organised are you?" and "Do you believe in … life after death?".

So far, the billboard has fetched between 15 and 20 "solid" applicants and many more had have wished him well even if not interested in a date, Mr Engle says.
